SPOTLIGHT.

Application filed April 7, 1921. Serial No. 459,456.

To all whom it may concern:

Be it known that I, KAI-ii. M. VVISE, a citizen of the United States, and residing at Birmingham, in the county of Oakland and State of Michigan, have invented a new and Improved Spotlight, of which the following is a specification.

This invention relates to adjustable lamps adapted to project beams of light onto any desired spot within a wide field, and its ob ject is to provide a lamp of this character and its mounting which may be so attached to a screen, especially to the windshield of a, motor vehicle or power boat, that the lamp on the front side can be manipulated from the rear side of the screen.

A further object of this invention is'to so construct the mounting that the lamp may be readily removed therefrom, and if provided with a cable of suflicient length, can be used as a trouble light.

Another object of this invention is to provide a simple and easily adjusted mounting which will not get out of order and which will hold the lamp in any desired position.

In the accompanying drawing, Fig. 1 is a longitudinal section of the lamp mounting attached to a windshield and of part of the lamp, the remainder being in elevation. Fig. 2 is a longitudinal section of a connector. Fig. 3 is an elevation of a slightly modified form of lamp. Figs. 4, 5 and G are central longitudinal sections ofother forms of lamp mountings which may be substituted for that shown in Fig. 1.

Similar reference characters refer to like parts throughout the several views.

While I have indicated a windshield pane 1 through a circular opening in which the lamp embodying my invention is mounted, it will be understood that it is equally adapted to be mounted in any other desired shield or screen. The body 2 of the mounting is in the form of a sleeve which has a flange 8 between which and the flanged nut 1 the screen may be gripped, the nut screwing onto the hub 5, which is formed with a seat 6 for the ball 7 providing a universal pivot. A bushing 8 forming a support and bearing seat 9 for the ball 7 screws into the outer end of the mounting for disposal concentrically with the opening in the screen 1.

Screwing this bushing in or out determines the firmness with which the ball is held in the mounting. In the claims I may refer to the assembly of the members 2, 1, and 8 as a housing, but since other constructions may be used, I do not desire to be limited to the peculiar type of housing shown and described.

A hollow handle member 11, preferably of insulating material, is mounted on the inner reduced end 12 of a supporting sleeve in any desired manner. The larger end 14 of this sleeve is pressed into the ball 7 and fits so tightly that considerable force is required to separatelthem. A lamp body 15 has a collar 16 at itsfrear endwhich is secured to the sleeve in any desired manner, and the sleeve is preferably formed with the well known bayonet slots 17. by means of which the light bulb 18 may be held in position. usual lens 19 may be mounted on the body 15 in any desired manner.

It is to be understood that no claim is made to the construction of the lamp or to thecontact block 10 within the sleeve 14, the block preferably being a cylinder with parallel metal tubes 19 in which the conductor wires 20 which enter through the handle may be secured by the screws 21. The con tact posts 22 are held out by the springs 23 to engage the two terminals 241 of the base 25 of the light bulb. A two contact lamp is shown because the lamp base cannot be grounded through a glass screen but any electrician can vary the construction to suit it for a grounded mounting. The plug 10 may be secured in position by a screw 26.

In Fig. 3 I have shown a sleeve 27 instead of the sleeve 14: of Fig. 1, and this sleeve 27 formed with a bend whose angle substantially may equal or exceed the angle through .which the ball 7 may be swung so that the beam of light may be projected at right angles to the screen or at substantially any angle between that line and a. plane parallel to the screen, this being possible by reason of the ball being freely rotatable in the mounting. When the angle of the bend of the sleeve 27 exceeds that through which the ball and sleeve 27 may be swung, it will be impossible to project a light ray at right angles from the windshield 1. This may be desirable in such localities where the projection of rays of light dead-ahead of motor vehiclesis forbidden.

In Fig. 1 I have shown a pin 29 extend ing from the bushing 8 into a groove 30 in the ball 7. When the handle 11 is rotated The V in either direction, the ball 7 and bushing 8 turn with it and so screw this bushing into or out of the body 2 and lock or unlock the ball 7 and the spot light. This is quite convenient as the lamp may be locked in any desired position from inside the vehicle.

Instead of a solid ball 7 I may use the construction shown in Fig. 6 wherein two shells 32 and 33 constitute a ball, either being slidable on the tube 12 and held away from the other by a spring The spring will be tensioned by the bushing 8 and the spot light may be held a firmly as desired.

In Fig. 5 I have shown a structure which differs from that in Fig. l in that the body 35 of the mounting is bored sutliciently large to receive a spring 36 which presses the cupped washer 40 against the ball 7, the spring abutting against the split ring 38. The bushing 39 is held in position by means of pins 37 which enter well known bayonet slots 41 in the front end of the body 35. The initial tension of the spring 36 determines the firmness with which the spotlight is held.

In the embodiment of my invention shown in Fig. t, the tube 4-2 is independent of the sleeve 44 and the adjacent ends of the tube 42 and sleeve i k are connected to the hollow hemispheres a8 and respectively. These hemispheres are kept in position by the spherical band s6 and are held more or less firmly in this band by the spring 47. The band d6 is held firmly in the seat d8 iirthe mounting 49 by a bushing 50,- also provided with a seat 51, and this bushing may be positioned by the pins. 52 engaging in bayonet slots in the front end-of the mounting. These bayonet slots as well 'as those em ployed in the structure illustrated in Fig. 5 are not detailed because of their v ry common use in the arts.

In each case, a ball is adjustably seated in a mountin" and while Figs- 1 and 3 show manual operable bushings to determine the firmness of the grip oi the mounting on the ball, Figs. 5 and 6 show springs for this purpose. Fig. t .shows two sets of sliding surfaces of which the grip of one is determined by a spring and of the other by a bushing.

The details 01" construction and the proportions of the parts may all be variedby those skilled in the art without dejiiarting irom the spirit of my invention as set forth in the following claims.

I claim I.
